Agent Based Kubernetes Installation
summary
Agent-based installation boots hosts with a discovery ISO, runs an agent to inventory hardware, validate networks and clocks, then configures nodes via a central assisted-service with API and UI. It uses Ironic for automated power/provisioning (Ironic integration), Ignition and RPM-OSTree for node files, NetworkManager for interfaces, and exposes CRDs so a controller can do Zero Touch Provisioning. The system tracks install pass rates (target ~75%), prevents bad installs before disk changes, and is used for OpenShift/OKD bare-metal clusters.
